抄録

Azo-, anthraquinone-, and phthalocyanine-type acid dyes containing an amino group were condensed with (1) or (2) in order to obtain new reactive dyes of general formula (3) and (4).(D=residual group of color component)These dyes contain two types of reactive groups; one, the 2-chloroethane sulfonyl group, and the other, the active halogen on the benzene ring. They dyed cotton in the presence of alkali by chemical combination, and the dyes of (3) type combined with cellulosic fibers through both of the reactive groups under mild dyeing conditions. Dyed fabrics thus obtained were very fast against acid and alkali.
